A nurse is providing teaching to a client who has type 2 diabetes mellitus and is starting to take immediate-release exenatide. Which of the following client statements indicates an understanding of the teaching?

Choice A rationale: Exenatide is administered via subcutaneous injection into the abdomen, thigh, or upper arm. Intramuscular injections are inappropriate as they alter the absorption rate of the medication. Choice B rationale: Most exenatide delivery devices must be discarded 30 days after first use. Keeping the pen for two months exceeds the stability period, risking drug degradation and infection. Choice C rationale: Unlike some insulins, immediate-release exenatide pens must be stored in the refrigerator even after the first use. Exposure to room temperature for extended periods reduces its clinical effectiveness. Choice D rationale: Immediate-release exenatide must be administered within 60 minutes before the two main meals of the day. This timing allows the medication to effectively slow gastric emptying and manage postprandial glucose.
